DOOR LOCK.

Application filed. April 25, 1922. Serial No. 556,517.

To ZZ wim/m, t may concern.'

Be it known that I, ARTHUR E. loonnUrr, a citizen of the United States, residing in Mount Carmel, county of New Haven,

and State of Connecticut, have invented certain new and useful Improvements in Door Locks, of which the following is a full, clear,

and eXact description.

My invention relates to door locks and l while the principles thereof may be more particularly applicable to vehicle doors, it

will be understood that do not confine myself entirely to locks of this type.

It is usual in the manfacture of door locks l5 for automobiles or other vehicles having closed bodies to provide means for locking the doors to prevent the entry of unauthorized persons into the vehicle. It is also common to provide what may be called locking handles, or handles having locks mounted in. the spindles thereof, which must be operated by the proper key before the handles may be turned to open the doors. In the past it has been the custom to lock the handle spindles or stems to the escutcheon plates, but a serious disadvantage in this method is that the escutcheon plate may be loosened or unscrewed readily and the handle may then be operated to open the door.`

In other forms of vehicle locks the door must be locked by a key from the outside, after it has been closed, and it sometimes occurs that the owner of the vehicle neglects to lock the door after closing it and thus the `vehicle is accessible for the entry of an unauthorized person.

One object of my iin'cntion is to overcome the disadvantages above referred to Aand to provide a lock, the. mechanism of which may be set to lock automatically when the door is closed, and also to provide a lock wherein thc locking or clogging device will be located within the lock or within the outer surface of the door where it will not bc subject to easy attack.

Another object of my invention is to provide a loclrlofvthis character with a ciogo'ing member which is located within theA lloclr mechanism and 'which may be actuated by a key operated lock mounted in the spindle of the handle.

A still further object of my invention is to provide means to prevent the bolt from being withdrawn by the door handle, which means shall be entirely independent of the escutcheon plate and to provide means for securing the handle in position in the lock which shall also be independent of the escutcheon plate in order that any'tampering with or loosening of the escutcheon plate will have no effect whatever toward overy Coming the lock.

Another object of my invention is to provide a vehicle door lock of very simple character and of improved operation.

To these and other ends the invent-ion consists in the novel features and combinations of parts to be hereinafter described and claimed. i

iig. 11 is a sectional view on line ll-ll ofNFig: 1Q., l 95 In the` illustration of a preferred eifnbodi ment o f my invention' have shdiv'n -a or tion of a 'vehicle door at l0 upon which is mounted L lock embodying my improvements. The parts of the lock mechanism may be supported upon a supporting plate 11 having a face plate 12 adapteil to be mounted at the edge of the door. Upon the plate 11 is slidab-ly mounted a latch bolt 13 in a guide 14 and in an opening l15 inthe plate 12. This bolt is provided with 4the usual beveled head 16 and is recessed at 17 Arearwardly ofthe head for a purpose to be hereinafter described.

As a convenient means tor urging the holt to protracted position, I have shown :acoil .spring 18 having one end thereof seated in a slot 19 provided in a stud 20 secu-red to the plate 11. The free end of the springis adapted to enter a recess 2l -int-he Ilatch bolt and bear against the shoulder 22 at the ft'or- Ward end of this recessto retain the bolt in `a normally protracted position.

The bolt retracting means inthe 'form shown is a :hub member 23 provided with a collar 24 j'ournaled in an opening y25 vin the Iplate 11 and a bolt actuating lever or finger 26 extending'into the recess 17 and bearing vagainst 'the 'shoulder 2T upon `one side ot the recess.

VSlid-ably mounted between the #guide lug 29 and the posts 30 on the plate 11 .is a dog- 0 Aging member 31 upon which jis provided a button 32 extending "through Ava slot 33 in the plate 11 fin :position to be manually engaged from fthe inside vof the door. The slideBl 'is' provided YWith a de'tent-f?)a which iis adapted =`to 'engage belor'v a shoulder 34 provided upon the hub 23 to dog Lthe hub against movement. The r'hu'b 23v and the slide 31 are retain-'ed in position lby being clamped between the mainsupporting plate 11 and a smaller auxiliar-y Ep'late "35, Which may be secured by screws '36 to lugs or 'posts upon fthe main plate. The :small plate 35 is provided With an opening Athrough which 'extends an oii'set vlinger 38 Aformed as an integral part of the slide 81. l The opening 37 is elongated, asshown in Figs. 5 to 8 to permit the reciprecation of this slide.

The colla-r '2401: the 'hub v23 is providedywith a square opening 39 in which is unounted 'a similarly shaped :stem 40 Which projects through Vthe plate 11 upon v'the inside of the door and upon which is secured the inside 'operating handle 41 'by means of the screw 42 andthe bushing or collar 43. At the lopposite 'end of 'the Vstem 40 is secured va. shell 4'4 which extends through the door and upon which is loosely mounted vtheescutch'eon plate 45 adapted to be secured to the outside of fthe-door by .screws or the Alike 46. A The outside knob 47 is provided AWith a 2ho'lloiv spindle 48 which is adapted to 'tele- `scopically receive the end 'of ythe-shell 44, lthe ytwo members Ebeingsecured 'together by bolt from the outside ot' the door.

the pin49. The spindle is provided at its inner end With an ornamental shoulder 50, which is adapted to abut against the outer edge of the escutcheon. Beyond this shoulder the spindle is formed With a slot 5l. to receive the lug 52 upon the shell 44, which in addition to the pin 49 provides for the securing of these parts against `relative rotation.

Within -the spindle 48 is mounted a rotary pin tumbler loch -52u consisting oli a pin tumbler case 5S and a key barrel To the 'inner end of the key barrel is secured a key rod 55, which extends into the shell 44 and 'Which-may have its end mounted in an aligning socket 56 in the end of the shell. Upon the key rod 55 which1 is preferably polygonal in shape is niountcd an actuating cam 57shownmoreespecially in Figs. 5 to 7, which is adapted to turn in a slot 58 provided in the shell opposite the odset portion v38 of the clogging slid-e.

lt Willfbe apparent that in the assembling of the parts ot the device, the loch 52". to-

gether with the key rod, maybe mounted 1 in the hollow spindle and thereafter the shell 44 may fbeconnectcd to the spindle by telescoping the adjacent'ends of these parts to some extent after the lug 52 has been aligned With the slot '51. The piu 4f) is fthen passed l'through the parts and the =escutcheon 45 lmay then he slipped over the end of the shell 44 'in position to be secured to the door. The hollow spindle or shell 44 'with the stein 40 extending therefrom `is then passed through the opening in the door and the stem 40 inserted through the openingSQ i-n the hub member 23 When the plate 111 IWiththeparts ofthe lock mechanism vthereon has -been mounted upon the door. The shell 44 andthe hollow spindle member 48, being rigidly interconnected, form in efiect a single spindle `lor operating the lt will be apparent that my lock ot' simple construction and at the same time possesses many advantages ot operation and may he lassembled 'with ease and economy.

The operation of the improved lock rfill be more or lesscobvious from the foregoing description. :It will be readily seen that when the parts are in the position sho-rvu in .F ig. 5, the latch 153 can be retra ed for opening the door by turning either die inside handle 411 or the outside knob or handle l? .47,'both of which are connected through the 'square stein 40 .to the latch retracting hub having the retracing lever or iin er 26. lVhen the driver'ot' the car intends to leave it fior some .time at thc curb or elsewhere,

the door having been opened by n'ianipulation of the inside handle 41, he can conveniently 'move the button 32 from 'the position shown in Fig. .2 to the opposite end ot the slot 38, thus moving -the (logging slide from the position shown in Fig'. 5 to the clogging position shown in. Fig. (l, wherein the detent 33" is moved below the shoulder to dog the hub 23 against movement. The door can be then closed as the bolt can be freely pushed in by contact with the strike plate in which operation the bolt is pressed back against the action of its spring away from the operating lever or finger Q6, which remains in the locked position. lllVhen the door has been closed, it will obviously be impossible to open it from the outside by manipulation of the outside handle, which cannot be turned without previous actuation of the key mechanism. Then the owner or driver returns to the car and desires to open the door, he inserts the proper key into the key hole 59 and turns the key barrel 54 so as to rotate the key rod 55 and the actuating cam 57, which in the locked position abuts the offset finger 38 of the clogging slide, as shown in Fig. 6. The cam, acting upon the offset finger 88 and being turned in the proper direction by the key, moves the slide rearwardly to its inoperative position shown in Fig. so as to release the hub and permit th-c same to bek turned by manipulation of the outer handle, as shown in Fig. 8.

It will thus be seen that the operation of locking the door can be carried out with maximum convenience from the inside of the car after the door has been opened by merely shifting a small button or thelike and then closing the door, after which the use of the key is a necessary incident to the opening of the door from the outside, as described. By having the key controlled locking mechanism act on the hub rather than on the bolt itself, the door may be readily closed without injury after the dogging mechanism has been set in the operative position, while the bolt is not retractable from the outside after the door has been closed except after previous use of the proper key.

If an unauthorized person attempts to a attack the lock by loosening the screws 4G, it will be apparent that the escutcbeon plate will rotate freely upon the shell la and the spindle 41-8 will not be loosened or affected in any way. IVhile the bolt is not dogged against retraction by contact with the strike, the operating hub is clogged against movement by the slide whichV is located within the door and which may not be successfully attacked unless access is had to the lock mechanism itself.

It will be apparent, therefore, that the improved lock combines great security against attack with maximum facility of operation, although the construction is relatively simple ancl inexpensive when the functions thereof are taken into account.

nWhile I have shown the lock as equipped with a clogging mechanism having a rotary `pin. tumbler lock to release the same from the outside, I desire to have it understood that I do not limit myself in all aspects of the invention to the employment of the pin tumbler lock, nor do I limit myself in all cases to the employment of a key operated lock housed within the outer knob or handle.

lVhile I have shown and described a preferred embodiment of my invention,it will be understood that the principles thereof are not limited to the exact details shown, which are capable of modification and variation within the spirit of the invention and the scope of the appended claims.
